    Video flicker CS5.5 Premiere.

    creazer Community Member

      Hi. I've been having this problem for quite sometime. I've tried many different things like changing the field order dominance, deinterlace, creating a new sequence straight from the clip, changing the speed duration, importing into after effects and using key remapping. I'll post up any more info if I remember later.

       

      Here is a Vimeo link to the clip I am talking about...

      http://vimeo.com/33338487

       

      I use the Canon XHA1 and film 50i DVPAL widescreen.

       

      I use Windows 7 on PC. My video card is NVIDIA GEforce 9800GTX/9800 GTX+(Microsoft Corporation - WDDM v1.1).

       

      Here are my project settings...

      My capture settings...

      capture settings.jpg

       

      My capture preferences...

      capture preferences.jpg

      Project panel info...

       

      project panel info.jpg

       

      When I right click on clip for the properties, I get this information...

      right click info clip.jpg

       

      My sequence settings...

      sequence settings.jpg

       

      I hope I've been able to give you all the information you need. I hope someone can even direct me into the way I would need to go to find out what's going wrong. The problem is most prevalent when I make it slow motion. I make it slow motion by right clicking the clip and changing the speed duration to 30 percent. Actuallu, I can change the clip to a few different percentages and I'll get the same flicker. Particularly at the top of the image. I can see the highlights, the trees in the background, detail on the outfits flicker especially. I know you should expect some, but this is definately more than usual. I hope the link to the vimeo video will help you see the problem.

       

      Please let me know if you need anymore info. Thank you...

          I forgot to add the h.264 settings for the vimeo upload. So here it is...

            I have just updated my drivers for my video card, exported a new clip and I'm still getting the same result.

              Please let me know if the jpegs are hard to see or if you need any more information. Does this seem strange? I have recently re installed windows 7 so everything on my computer is new. I went to control panel and device manager and then right clicked my video card and updated my drivers. Is that the correct way to do it? Would anyone know of anything else I can check?

                Did you deinterlaced or use Flicker Removal the photo's and slomo footage on the timeline in the Field Options?

                Cant read your export settings.

                 

                I would edit in HDV and export to DVD, this gives a better result then downconverting in the camera.

                  For slowmo you should probably check 'Frame Blending' and preferably do that in a nested sequence which is not interlaced. Also, you should enable Frame blending in your export settings as well.

                  If everything else fails, de-interlacing your footage before importing in PPro helps.

                   

                  Good luck

                    No i disagree, the A1 (which i happen to have also) is a tape camera everything is interlaced so leave it interlaced.

                    And no frame blending on export that is for when using different framerates.

                      Doing ist that way would be fine if the output would be interlaced as well, which it isn't. By staying in interlaced mode you'll never see your movie the way it will be until you export it in the end, the result is shown above.

                       

                      Bottom line: somewhere along the road you'll have to do de-interlacing and I'd prefer to actually see any problems doing so as early as possible.  Furthermore, you are actually changing from 50 fields per second to 25 frames per second, reducing the perceptible motion by 50 percent and having some time remapping done as well; using Frame Blending does ceate a much smoother result, especially for the time remapped parts of your video.

                       

                      On the other, if you had progressive footage I'd only apply the frame blending on the time remapped clip, here Ann is quite correct.

                        Hi Ann. Thanks for your reply. Were you able to see the video link I put in the post? The Vimeo link? We're you able to see the flickering? I'm definitely going to do what you advised. Thank you. I will try it with the next job I edit. I'm just asking so I can keep my eyes open for anything else.

                          Thanks for your help mate. I will definitely try and get the right settings for the clip and make sure I don't down convert it to 25 frames.

                            H.264 is a funky compression codec to say the least. Try expoting as a P2 Format and see if you get the same result. That will let you know if your settings are bad. Having said that I noticed the top border of the video jiggles up and down.

                              Ok. Thanks.  Do you think it could be with the way I captured the footage. It was filmed hdv pal 50i and when I recorded it in I down converted it. Could that be the problem?

                               

                              Here is another screenshot of my export settings and I have made it a higher quality one.

                              high export settings.jpg

                               

                              Actually, it does say field order progressive. That would be a problem wouldn't it? Especially if I filmed it interlaced. Were any of the other screenshots difficult to read? Also, is this screenshot easier to read? Please let me know if it's not and I'll type out all the information.

                                Hi Medeamajic, why do you think the top border of the video jingles up and down? Could it be because I'm down converting the video when I'm capturing?

                                  I just captured some hdv as recorded and it says in the project panel that the frame rate is 25fps. So the frame rate didn't change in either instance. Were you saying that I recorded it at 50fps and then when I captured it, I down converted it to 25fps?

                                    hi Ann, I didn't deinterlace the video. I didn't reverse the dominance. I did slow motion the footage. Basically I right clicked the video on the timeline and I then changed the speed duration to 30 percent.

                                      The screen shot was hard to read. I don't know for sure why you are having problems. Try turning off the GPU acceleration if you have it turned on. See if that helps.

                                          What happens on export if you opt to match sequence settings?

                                            Don't use Match Sequence settings, set everything manual or use a preset.

                                            Stills and slow motion in a interlaced timeline needs to be deinterlaced (Field Options) on the timeline.

                                            In export always use Max Render Quality and VBR2pass.

                                            What do you need the H.264 for?

                                            What is your final output going to be?

                                              Hey Thanks for the advice. Ok. So I'll set everything manually.

                                              I use the h.264 for vimeo upload.

                                              My final output will be DVD mpeg.

                                              So basically, you're saying that if I slow my footage down to 30% by changing the speed duration, I need to change the field options to 'always deinterlace' even though I filmed it interlaced? Would that be correct? There are no photos in the video that I have uploaded on vimeo. The sobjects are just standing still because they're taking a photo.

                                                I've actually started a new project and recaptured the footage as it's native hdv. If I  now export the footage and click match sequence settings, it gives me a large mpeg file.

                                                 

                                                Also I checked with a fellow editor about what you said about the down conversion. My Canon XHA1 films 25fps 50i HDV and when I down convert it, it should still be 25fps SD 50i. Is that correct? That's what my friend is telling me. Just trying to see what could be the problem.

                                                  Saad Khan, I don't think I said anything about down converting. I just wanted you to experiment to see if the end result was always the same as a process of elimination.

                                                      Read my previous post again.

                                                      Capture in HDV, edit in HDV (50i timeline) export to mpeg2-dvd (do NOT use match sequence settings, or preview files).

                                                      Use an export setting like DV pal widescreen (or set it manually) and set Use Max Render Quality (hidden in the wing menu of the export settings) on.

                                                      For Vimeo use the YouTube preset or a HDTV preset under the H.264 format.

                                                      Especially working with interlaced material, for slomo's/freeze frames you generally set Always Deinterlace on the timeline or use Flicker removal, whatever works best. Its trial and error. You might want to experiment with Frame Blending (right click on the clip in the timeline)

                                                      http://help.adobe.com/en_US/PremierePro/4.0/WS9393E273-9D4D-42f1-AEE5-6B2F9B8D4F46.html

                                                       

                                                      Your camera downconverts from hdv 50i(nterlaced) to SD 50i. There are 50 fields in on frame, and there are 25 frames in one second. Medeamajic is confusing you. What your friend says is correct.

                                                        Thank you so much for your helpful advice Ann. I really appreciate it. I will definitely be doing all that you suggested. When I export my HDV sequence to mpeg2-DVD, it exports it as 720 576, and does't allow me to change the size. Is that right, when HDV is 1080 ... Is that a problem? I find that after export, there's a thin black end at the horizontal ends of the clip. However, you can't see the black lines when you play it on a tv. I think I've resolved the h264 settings. The default settings for the h264 were 526 720 and I changed them to 720 540 and there was no more flicker. However, that still didn't solve the issue with the flicker of the sd sequence. The link you sent me with the info on interlace footage and what to do with the sequence settings was great. Thank you. I'll also experiment with the H264 footage with the presets you suggested and see how that goes.

                                                          DVD IS 720x576 for PAL.

                                                          The thin line on the edge is correct. You can get rid of it by cropping in the export settings. But first things first.

                                                          Use these settings when timeline is SD, see screendump.

                                                          When timeline is hdv use YT HD widescreen preset.

                                                            Thank you Ann. I notice that your fild order is progressive and your source footage is lower field first. Is that correct? Also the level is 3.0    my level is 3.1

                                                              SD is always lower field unless captured with a Matrox.

                                                              So when going to dvd, fields should be set to lower in the mpeg settings.

                                                              If you are editing HDV and going to dvd, fields should be set to upper in the mpeg settings, because HDV is always upper.

                                                              For Vimeo etc movies need to be progressive in output, if you leave it interlaced you get the comb-effect.

                                                              You can raise the levels but if you raise them to high it will change the settings like framerate and resolution in the settings.

                                                                SD is always lower field unless captured with a Matrox.

                                                                 

                                                                Slight correction.  DV is always LFF.  Standard def MPEG material is often UFF.

                                                                        But if interlaced material in Vimeo gives better result; so be it.

Or did you mean to crop the top? Anyway, that's the least of my worries. For now, I'm able to produce better quality DVDs!
