    What to do with MP4 Source Files

    Beau2013

      I usually edit avi files, but a friend has asked me to edit a batch of mp4 files that were taken on a little Samsung camcorder. I'm not sure what presets I should use, but nothing seems to look good when I experiment. Any suggestions?

          Lots of information needed to address the question properly.

           

          What version of Premiere Elements are you using and on what computer operating system is it running?

           

          What are the properties of these .mp4 files...video and audio compressions, frame size, frame rate, interlaced or progressive, pixel aspect ratio? What is the model Samsung that these .mp4 files are coming from?

           

          What type of edits of the video are being requested and what is the intended export of these edited files from the Timeline?

           

          Suggestions will follow according to the details that you provide.

           

          Thanks.

            I'm using Premiere Elements 11 on a Win 7 desktop.

             

            The camera on which the video was taken is a Samsung SMX-F30RN/XA C

             

            I've scowered the user manual and there's little said about the MP4 format other than the Video Compression format is H.264/AVC and audio is AAC (not sure that's meaningful).

             

            I was originally planning just to combine the 40-odd individual MP4 files, cleaning up errors and introducing transitions, perhaps a few titles.

             

            Thanks for taking the time to help.

              That was one hard camera to find specs for.

               

              I found the User Manual for it. Apparently you have either 720 x 480 4:3 or 16:9 at 29.97 interlaced frames per second (described as 60i). Do you know if 4:3 or 16:9?

              You can check to find out by getting a properties readout from MediaInfo, looking specifically for display aspect ratio 4:3 or 16:9. Also, you appear to have "interlaced video", so we want to know if the Field Order is Upper or Lower Field First. The Media Info readout will also tell us that.

              http://mediaarea.net/en/MediaInfo

               

              Overview...open Premiere Elements 11 Windows, go directly to File Menu/New/Project. In the new project dialog, set for NTSC DV Standard or NTSC DV Widescreen depending on what your video properties are. Before you exit the new project dialog, be sure to put a check mark next to "Force Selected Project Settings on this Project". Then, when you are back in the Premiere Elements Expert workspace, use Add Media/Files and Folders to bring your video into Project Assets. From Project Assets, drag you video to the Timeline.

               

              If there is an orange line over (I am not referring to an orange line through your video), then press the Enter key of the computer main keyboard to get the best possible preview of the playback of your video in the Edit Mode monitor.

               

              How are you going to export your Timeline.

               

              Please view the above. Any questions, please do not hesitate to ask.

               

              Thanks.

                DV Standard worked great. I thought I'd tried that before but I may NOT have put the Force Settings checkmark on.

                 

                I plan to upload it to my website as an MP4 for them to see online. Then I'll burn a DVD.

                 

                Thank you for your detailed advice.

                  Your news was excellent.

                   

                  Please do not hesitate to let us know if you have further questions on any of your Premiere Elements workflows.

                    It Looks like I'm not out of the woods yet.

                     

                    I was able to edit just fine, My first export was to an MP4 file using the MP4-NTSC DV Standard preset. I was able to play the file on my PC as well as upload it  to my webvsite and it played beautifully in both cases.

                     

                    Next I tried burning a DVD. I used the NTSC_Dolby DVD preset and Element 11 burned a DVD for me. Trouble is, when I view the DVD on my TV, all camera movement causes blurring of the image. Finally, I exported to an MPG file on my PC, using the NTSC DV Standard preset. That file has the same effect of blurring with camera movement as the DVD.

                     

                    Thank you for any help you might offer.

                      I think that is because your MP4 source is compressed, and then you compress again to create MPG/VOB on a DVD

                       

                      Squeeze a loaf of bread, and then squeeze the resulting lump again... result doesn't look much like a loaf of bread

                        What did you burn to DVD-VIDEO Standard on a DVD disc....

                        a. the SD mp4 file that you exported from Premiere Elements Timeline using as source media the original SD .mp4 file

                        or

                        b. the original SD mp4?

                         

                        In other words, did you use the same project with your original SD .mp4 file,

                        first export the source to the SD .mp4 file saved to the computer hard drive

                        and then

                        came back to the same project and burned that same Timeline, this time, to DVD-VIDEO Standard on DVD disc?

                         

                        At this point, the answers to all the questions that I asked back in post 1 would be helpful, especially if you started with interlaced video and the Field Order was Upper Field First instead of Lower Field First. If there is any chance of getting a MediaInfo properties readout for your source .mp4, that would be very helpful.

                         

                        For interlaced video, we might call Field Options/Reverse Field Dominance or Always Deinterlace into action.

                         

                        More later.

                         

                        Thanks.

                            The following may sound "a bit" different but let us see what happens...

                             

                            Start a new project in Premiere Elements 11.

                             

                            Set the project preset manually by going to File Menu/New/Project and selecting as the project preset

                            NTSC

                            FLIP

                            Flip Mino and Ultra 29_97p

                            Make sure that before you exit the new project dialog that you place a check mark next to "Force Selected Project Setting on this Project".

                             

                            When you get back to the Premiere Elements 11 Expert workspace, import your original .mp4 video into the project with the program's Add Media/Files and Folders/ to get the file into Project Assets. From Project Assets, drag the file to the Timeline.

                             

                            For the first export from this Timeline,

                            Publish+Share

                            Disc

                            DVD

                            and burn to: disc

                            Preset = NTSC _Dolby DVD.

                            Does that look any better?

                             

                            I would stay with the AVCHD.mp4 export for saving a file to the computer hard drive. But, if you want to experiment with a MPEG2 export, then check out

                            Publish+Share

                            Computer

                            MPEG

                            Presets = HDTV 1080p29.97 High Quality

                            and then the Advanced Button/Video Tab set accordingly

                              Hi ATR,

                               

                              Using the Flip Mino and Ultra 29-97p preset was the magic sauce! The DVD is now of the same quality as the MP4 file on the web. By same quality, I mean it's as good as that camera allows it to be. Once you get used to HD cameras, it's hard to go back.

                               

                              Thank you very very much for taking the time to give me all this advice. I've learned a whole lot and my friend has a DVD that wouldn't have been possible.

                                Often one cannot go by the book, but rather needs to go by the details of the specific situation in order to customize the reply to the specific situation.
