Adobe Premiere Deinterlacing/youtube/HDV quality problem

[qatzo]

Hello,
I am capturing video from my TV in mp4 format, with 1080i(60) quality. After I save it to my hard drive, I import it to Adobe Premiere 5.5 as HDV with that quality. I want to upload the video to Youtube in 1080 quality. Here are the things that are happening now:
--If I upload the original video (without exporting), the 1080p quality is perfect.
--If I export the video in Premiere (checking the "match settings" box), the 1080p video has horizontal lines (despite Youtube supposedly having a deinterlacer). However, 720p video looks fine.
--If I go under the "clip" menu and click "Always Deinterlace," then export, the 1080p Youtube video looks alright, but the frame rate is halved (I think). 720 also looks fine here.
--*Also, if I import the video as 1080p, the framerate once exported/uploaded is worse.

It seems to me that if I can upload the original and retain all of the quality, I can export it using Premiere and do the same.

Help anyone?
thanks

the "framerate" of 60i is 30 "frame" per second. the "60" refers to fields. 2 interlaced fields make up a single frame. when de-interlaced 60i is 30p.

what you have isn't HDV (1440x1080 30i). try a template that matches your input. and export as 1080 30p.

In the USA, an ATSC or QAM tuner file is probably 1920x1080 60i or 1280x720 60p in MPeg2 TS format. Check with mediainfo.

Set Premiere custom project settings to match the source spec.

For Youtube export set 1920x1080, 29.97 fps, progressive, 1.0 pixel aspect, with h.264 codec. Keep bit rate high ~15,000 Kb/s (reduce if Youtube file size limit is reached).

When you upload the original, Youtube is deinterlacing to 30p and recoding to low bit rate.

Most people complain about Youtube's deinterlace, saying results are better if you send them 29.97p h.264. If you do, keep bit rate high because they are going to recode again.

those are my video specs. @aedipuss, when i said 1080i 60, that was a typo. I know I have 1080i30.

what should I set the multiplexer for? (between mp4, 3gpp, or none)

[edDV]

1080 60i, 1080 59.94i, 1080 30i and 1080 29.97i are all the same thing.

What captured that way? Is it a Hauppauge HD-PVR?

Mediainfo says resolution was reduced to 720x480i.

yes it is

Mediainfo says resolution was reduced to 720x480i.

does that mean I can't get 1080 quality?

That's exactly what it means. You went from HD to standard def.

[qatzo]

You went from HD to standard def.

why is my HD PVR recording in standard definition??? that file was right off my hard drive
as I'm recording, it says Input Resolution: 1920x1080

Somehow you asked for SD.

I don't have an HD-PVR here to test. Others do.

that cant be true. when I upload it to youtube, 720p IS HD, and is noticeably better than 480.

hehe you've mixed up the vertical and horizontal. "720p" is measured as vertical to be HD, what you've got is 720 horizontal with 480 vertical. so no you have lowly SD only.

I know how to measure video quality. The youtube quality is just as high as other 720 videos I've seen

no. the video specs you posted are strictly SD.

well then now my problem is: why are the specs wrong?

...

I never noticed Mediainfo report "Original" width/height before.

I don't think MediaInfo is capable of detecting that info it unless it is written in the header. I did a search and found that Quicktime will write that sort of info when making conversions.

why would you think you're smarter than the mediainfo and everyone here? you've mad a mistake in setting up the capturing program and it is recording in SD. fix your error if you wish to capture HD.

[budwzr]

The HD-PVR records to whatever the source is.

[qatzo]

my computer has well above the specs needed to record in HD, and my TV is set to 1080i. I don't think I'm "smarter" than Mediainfo. After uploading the video and watching it in 720, I compared it to other 720 videos captured by a Hauppauge HD PVR and found that the qualiity was just as good, if not better

I may be a noob at video coding, but I know HD quality.

*Also, if I check the "match sequence" box, Premiere sets the pixel ratio to 1440x1080 (?)

With the HD-PVR all capture encoding is done in hardware. The resolution would be set in the Hauppauge software. The capture file should be evaluated by mediainfo. You can double check with VLC media information or GSpot. If the file is 1920x1080 60i, set Premiere project to 1920x1080 29.97 upper field first. For export encoding for Youtube you can test various settings.

Option 1. h.264 1920x1080 29.97 fps progressive

Option 2. h.264 1280x720 29.97 fps progressive

or send interlace and let them deinterlace it.

1440x1080 is wrong unless that is what you told Hauppauge to capture.

Mk I think I've got it worked out...
I'm exporting h.264 1920x1080p 29.97 fps but the frame rate at 1080p (versus 720p) on YouTube always takes a hit... I've just decided to export as 720 because it's almost as good. Thanks for all the help, especially edDV
