Uploading M2TS to YouTube
on May 11, 2014 at 5:42:11 am

I have a raw clip in M2TS format, when i render this through sony vegas to MP4 and upload it to YouTube i notice the M2TS has better quality. Hows that happen when its not even on the supported format list? The raw clip is 60fps and the MP4 is 30fps both dont really playback smooth as expected on YouTube, does it drop every other frame when its re-encoding 60fps? Appreciate any help.

It probably is. Dropping every other frame is a common way to get from 60p to 30p. You're never going to get the same quality on YouTube as the original source.

Thanks for the advice, I understand original quality cannot be achieved on YouTube yet i have seen some amazing quality out there usually from channels with millions of subscribers. Do they just know the perfect render settings or do they get superior encoding when they upload to YouTube? I have also noticed when i upload the same video at different bitrates, the lowest (4Mbps) had the least pixelation as oppose to the others (10Mbps) & (20Mbps) as these are in MP4 format i would have thought *High* profile would be best as it is recommended for YouTube, yet i get better results from the *Main* profile. Im using the *Internet HD 720p* template, should i use the deblocking filter & enable progressive download? also not sure if i should use *Two-pass* bitrate, appreciate the assistance.

I would start with the Sony AVC "Internet 1920x1080-30p" template that is build into Vegas Pro. Sony has tweaked these Internet templates to get the best results with on-line video sites like YouTube and Vimeo. You can always use Two Pass to make the most of the average bit-rate but it's not needed (and not available) with Sony AVC. I assume people who are getting good video quality are following YouTube's Advanced Guidelines and not just guessing. They also might have premium accounts that get them better encodes? I don't know. The Sony AVC template is very close to the settings that YouTube recommends (High Profile, CABAC encoding, etc.).

Not sure why but i dont have the template you suggested, Im using Vegas Pro 11 as i dont have a 64-bit system. I tried the Two-Pass and considering it takes twice as long to render and doubles the file size, i didnt actually notice a difference in quality. From what ive seen Vimeo has great encoding and playback is almost as good as the original source, however i wont be uploading to this site as YouTube is the *go to* site for online video. As far as i know YouTube doesnt have premium accounts so i guess they are following the advanced guidelines, could the fact that im uploading gameplay from call of duty be the reason the guidelines aint working for me? perhaps they are recommendations for GoPro footage etc, Thanks again for your time John.

That's because that template is on Vegas Pro 12.0. ;-) If you're not using the latest version of Vegas Pro, you should mention it your post so that people don't recommend that you do things that won't work.

For Vegas Pro 11.0 use MainConcept AVC with the Internet HD 1080p template. This template will allow the Two-pass option for better quality.
