(HDV) awesome looking footage in 3.5gb .m2t file. looks like s**t on youtube

hey guys, i made a really cool video about deloreans.  it's 20 mins.  the 3.5 gb .m2t file i have of it looks outstanding....it's night and day to the jittery/image-quality-challenged clip i export from premeire using the h.264 youtubeHD preset.

 

any advice?  it's a really awesome video, and it's killing me it looks subpar to what i'm looking at on my computer

the filesize of the youtube one is around 850mb

Hi Brian,

Have you checked the You Tube guide lines, not sure you can upload such a large file.

Here are some things I would try.....

Initially I would try rendering the file in a different codec, then try it again on your tube...

If its still bad then try just a 30s clip on a on your normal codec, if its still jittery then try another codec, if other codecs fail then it is likely something wrong with the video :(

But I would definitely check the you tube guide lines....

Good Luck

I render out to mp4 for upload to Youtube  1280x720  but you can do 1080i as well, but I don't see the point, most people won't watch in in HD, and even if they do 720 looks fantastic on the computer screen.

Look here: alternative to U-Tube

regarde ce site il y a des démos a des alternative de U-tube.

Brian,

MTS is a terrible format for editing. It starts to fall apart as soon as you try and chop it. The workaround I found was to encode all your footage to an intermediate format that is easier to chop. Having said that, the workflow was too much, so I ditched that camera as fast as I possibly could. 

It was the same as yours: previewing in Media Player Classic, it looked amazing. Preview in Premiere, it would start jittering. Just an idea, I found that Nikon DSLR footage acts the same way, until it's dropped into a timeline with the same characteristics. 

eg> Nikon Footage: 1080p 29.97 progressive footage, H.264 codec, in a .MOV wrapper. If the timeline was 1080p drop-frame(29.97f/ps) then it would preview, and edit fine. A vanilla 30p timeline would cause a constant jump to the footage. I can't comment whether it rendered out any differently. I never liked Nikon DSLR footage because it was too soft.

I never liked my HDV MTS files because once they were deinterlaced, they looked soft, and lacked detail. 

TLDR: Figure out exactly what you're getting from the camera, and make sure that your sequence settings match. If it's 60i, then edit in a 60i sequence. 

I have zero experience with Final Cut Pro, so keep that in mind. In premiere, the H.264, Youtube Widescreen HD preset is very nice, and can be reduced to 256kb/sec with still decent results. I think your best bet for quality is H.264, that way when Youtube lowers the bitrate substantially, the video you've uploaded is already using the same compression scheme. Going from H.264 M2t, to Mpeg4, then to Youtube's FLV H.264 adds the artifacting and garbage from each compression scheme. I've never had much luck uploading Mpeg4 to youtube...it seems to 'like' the H.264, in a .mov wrapper. 

Compressor seems to give more erratic results. I moved to progressive cameras, without interlaced wrappers, that eliminated the problem. I use an H.264 file in a .mov wrapper to upload to youtube, at qualities of .8 - 7mb/sec, in 720p, and 1080p. 

On a side note, if you give Youtube a 1080p file, then you'll get a better 320p video. If you give them a 320p video, then the recompressed 320p output will be worse than what you gave them. I know people tend to watch videos at only 320p, but I go with the rule of keeping generation loss to a minimum, or keeping the most quality, until the last possible stage. 

Edit*** Just realized you're using HDV, so mpeg-2 miniDV...AFAIK, even if you're rolling progressive, it's written into an interlaced file..could be wrong. Youtube doesn't handle drop-frame, or interlaced footage well. Unless you're going in with 1080i footage, and even then I've had 1080i uploads come up looking worse than SD. Make sure you're using your superior frame-blending, and de-interlacing algorithms, and give youtube progressive, 30 or 24p footage, non-drop frame.
