Thank you beforehand for your time.
I am uploading sporting videos on YouTube particularly snooker.
The videos are captured with a high quality videocamera and then edited with Adobe Premiere CS4.
May I ask two questions:
1. Which are the best export settings for Youtube when using a Full HD source file (1920 x 1080) at 30 frames per second ?
For the export file I use the same width and height as the source file i.e. 1920x1080.
However, the original file is shot @ 30 fps but I read somewhere that I shoould use 59.94 fps for the export file and it seems to be working although it doesn't sound right, does it :-)
My current settings for my export file are:
Main Concept H.264 video
Width and Height : 1920x1080
FPS: 59.94 fps
Pixel Aspect Ratio:Square Pixels
Bitrate Encoding: VBR, 1 Pass (I also use 2 as it doesn't make matters worse it just takes longer to render, pls correct me if I am wrong)
Target Bitrate: 4.8
Maximum Bitrate: 8.2
KINDLY PLEASE CORRECT THE ABOVE SETTINGS AND EXPLAIN WHY IF POSSIBLE, MANY THANKS :-)
2. Is it normal that the export video plays great on my PC but when uploaded on YouTube it skips frames and seems a bit choppy?
I have watched many clips on YouTube at 720p or 1080p and the seemed v good, when I watched mine it was not playing as smoothly as it does on my pc.
Is this something I have to keep in mind so as to assist the YouTube player by chnaging my export settings.
Kindly please comment on the above and also watch my videos for your comments on how to improve the quality.
THANK YOU FOR YOUR TIME!
Best wishes form Athens Greece,
The videos are captured with a high quality videocamera
what is the camera brand and model number ?
can you post a screenshot of your video source footage using GSpot ( free program ) here ?
I think that's the first thing to deal with as it looks like your original footage is interlaced and before going further it would be good to confirm what your source footage is...
Thanks for your reply :-)
I use the Sony handycam HDR-XR520VE.
I have downloaded the GSpot software but I do not understand how I can capture a screenshot.
I run gspot, then I open my video from gspot and a table with information appear. I then take a snaphot using the PrtSc button on my keyboard, I paste the image in MSpaint I chnege the width and height to match the requirements but it does not upload.
so would like just a screenshot of my movie, like a still image ? I am only asking because I have posted the link on youtube and you can watch the video if you like or take a still image.
sorry for not getting this fast ... :-)
Thanks for telling what you shot footage with.
The screenshot would be putting the video into gspot , hitting the prnt screen button, opening an image program like photoshop, choose file / new ...it should automatically "see" whats in the screenshot (copied to computer with prnt screen ) and open the new file with the correct dimensions...no need to adjust anything...when new "file" opens then "paste" into the new file...you should see the screenshot in the new file...
crop it so its just the info you want to save and then upload it to this forum..after saving as JPG image on your desktop or somewhere easy to find...
I think Ann's suggestion to export is what you should do...
---------------------she said -------------
There is a preset for YouTube HD widescreen under the H264 format
Use that, it works great.
However, I don't think you have the correct project setting to begin with, and that may have some big effect on your export.
The GSpot screenshot didnt tell us what we wanted, which is what your source footage is...and you could try---- mediainfo -----instead, another free program..and use the "tree" view to see all the details of your file.
Since I didnt get to see the specs of your footage I googled your camera brand and model and came up with some facts that suggest you may not have the correct project settings to start with ....which may have an bad effect on your exporting....
Your Gspot screenshot says you have a filename extension of mt2s, which is avchd , and then confuses me with the mpeg-2 transport stream, mp2t..info.. so maybe the free program----- mediainfo-----can tell us more. We are looking for exact specs of the footage which will probably look something like this:
1920x1080 interlaced 60 fields, 16:9, 30 fps, 16,000kbps ....
Here is what sony says about your camera basically ( as far as we care about it at this moment )
sony handycam HDR-XR520ve
Format : HD: MPEG4 AVC/H.264; SD: MPEG2
Video Signal : HD: 1920 x 1080/60i
SD: NTSC color, EIA standards
High Definition, AVCHD (1920 x 1080, 1440 x 1080) / Standard Definition, MPEG2
240GB Hard Disk Drive, Memory Stick
HD ; FH (1920x1080i, 16Mbps) / HQ (9Mbps) / SP (7Mbps) / LP (5Mbps) , SD ; HQ (9Mbps) / SP (6Mbps) / LP (3Mbps)
Note especially that according to this your camera shoots HD interlaced footage at 30fps. When you set up your project in premiere it should "match" the footage...and the specs of the footage. If your source footage is SD ( mpeg-2) --then you should match THOSE specs.
When you export progressive ( for the web ) you will lose half your interleaved fields...which essentially means you need to export a frame size "half" the size of your original footage to keep nice quality....But we are getting ahead of ourselves, because before exporting considerations it's important to make sure your original footage is in a project that matches that footage...
That is probably why I thought I saw ( on youtube sample you have linked here ) interlaced artifacts in the video...?
After you get the right project settings, once again, I would try what Ann suggested in her post to you ! Good Luck !
ps...youtube is progressive for watching on computers, and if you want to burn a blue ray, you could burn it interlaced and let the blue ray player deal with the sending the right signal to the digital tv ....in other words, you keep the frame size on export for blue ray...but for progressive you may have to half the size of the frame ....hope that makes sense... also ---youtube will reformat your video no matter what you give them...but usually they convert everything to mp4 and so the preset Ann speaks about will probably be mp4 so there is less fudging by youtube when they get it...
Dear Ann and Robodoq2,
Thank you for your efforts and for sharing all this valuable information.
I used the media info software as suggested to give you my source footage details attached below.
I will try the settings Ann suggested and let you know how it worked out however these settings (YouTube Widescreen HD) are set to 720x480 only. Can I go for 1920x1080? <-- will that affect the outcome negatively ?
Given the below details could you kindly suggest what are the best project settings for me to begin with?
As I understand it is very important to begin with the project settings which match my original file. Is there something that I should be extra carefull about?
For example, I noticed that media info says that the source footage is video stream AVC.
However, I am still not sure which pre-settings to use for my projec (AVCHD, AVC-Intra) and at what other specs:
2. Finally Robodoq2 you said:
"When you export progressive ( for the web ) you will lose half your interleaved fields...which essentially means you need to export a frame size "half" the size of your original footage to keep nice quality...."
Kikndly please elaborate on that comment, does this have to do with the frame rate or the frame size ? what is the frame size of the original file and how do I reduce it ?
PS. What position shoulf the constrain widht and height button needs to be at?
MEDIA INFO - SOURCE FOOTAGE
Thanks for all the info....that helps a lot...Im gonna hope Ann helps you with this project setting because I dont have cs4, I have cs3..without avchd presets...which is probably what you'll use...
you want 1920x1080 25 fps (24.97 ? ), top field first (interlaced), etc..instead of 1440x1080 progressive like you have picked on screenshot...but let Ann tell you which preset to use as I dont have cs4 and she is familiar with this format I think...
With regard to the video interlaced in general...there are two pdf files on this internet website page ( PDF FILES ) that give the basics of video info...
When you have the time breeze through them and you'll see what you're dealing with...
Ann may also have suggestions for using cineform with premiere cs4 for BETTER results but that's sorta another issue...and may not apply for an export to the web like this case..
Thanks you so much :-)
The pdfs seem great !
Since the software "media info" showed that my source footage has Scan Type: Interlaced this means that my camera can only record interlaced and not progressive scan I take it, therefore I will try and maintain the same exact specs of my source footage to my project. Makes perfect sense,
To Ann: Is it AVC-Intra or AVCHD the one to go for ? Thanks
I would be very interested to also know about cineform or any other settings for better movie quality to on TV (quite new model) or burn a Blue Ray disc.
I have tried a Blue Ray setting and the quality was amazing however the video was moving very SLOW slower than it should be :-(
Any suggestions are welcome.
In the meantime thank you agian for your time.
you are welcome
interlaced was sorta invented for use with broadcast tv and the quality is very good, and sometimes even better than progressive ( even today ) if there is a lot of 'Action' in a scene ( less blur in single frames if you look at the single frames to compare )..also, most DVD's to date have been burned from interlaced footage and many blue ray are too....
The dvd player or blue ray player can figure out what sort of tv it is hooked up to ( digital widescreen tv or old 4:3 crt tv ) and deliver the proper signal to make it all look good...
So there's no need to think progressive is automatically BETTER than interlaced...it depends on a lot of stuff...
lets see if Ann weighs in with cs4 settings for you ...while you read more of those pdf files , hehe...you will be expert in no time !
ps...if you feel like it , check out the color sampling info ( you have YUV and 4.2.0
I mention this as it might help later re: good color reproduction on your exports ( your youtube color was a little over "saturated" IMO...very very green and very very red )....so at some point maybe that can be fixed up a little bit too...
I was going to say that these pdfs will make me an expert he he
Also thanks for clarifying that interlaced is not automaticaly worse than progressive, as I thought it was (u got me there)!
Thanks for your time once again!
You have PAL and in the U.S. we have NTSC....that's what Ann meant by saying NTSC is 60i ....just pointing out the difference between countries ( standards ...which is based on our electric grids -- power from wall socket )
Thanks Ann !!!
when you get your project done export as Ann suggested to that youtube preset....and yes, you have to reduce the size of the movie, I would stay with the default ( I think you said 720x480 16:9 ? ) and if you have choice leave it --"main" high and level 4 (same as source)
For Blue ray it would stay the same dimensions and be interlaced ....I believe....and in general you would export other stuff for PAL probably...
SD would be 720x576 I think... good luck !
One more clarification though (let's see if I leraned anything the last few posts......)
One can have a source video interlaced and yet export it with Premiere CS4 as progressive (correct me if I am wrong)
As I see it one would only do that just so Youtube doesn't convert it to progressive itself and hence one can achieve better quality on YouTube.
However what would be the best way to do it if you are only going to watch it on PC or other players ?
I.e. should you set the export file with scan interlaced so as to match the source file ?
Which will achieve the better outcome ?
I made a couple of tries i.e. matching source scan and export scan and also other settings such as frame rate etc and also one try where I used a source footage with interlaced scan and export it with progressive and I so little difference. I think matching source and export settings was slightly better though more crystal clear!
Best wishes ! !See u
hmm, well, that's a boatload of stuff to cover...
yes, progressive for youtube ( probably is set that way for the preset export to youtube, with reduction in frame sizes to accomodate - bitrate is probably already set also, and cbr, or vbr stuff )
yes interlaced for dvd and blue ray...match footage.
yes progressive to watch in a media player on computer, and again, reduce the frame dimensions to half your original...dont use mpeg 2 for that, as that is basically to burn discs...try microsoft wmv etc
Hopefully you are using encore for any dvd blue ray burns...that will make life easier for you.
note: if you watch interlaced footage exported for burning a dvd or blue ray on computer with a media player it will look horrible probably...you have to burn the disc and look at THAT to see the real quality.
