Converting 1440X1080 to PAL 720X576

[TVBroadcast]

Hello,

I have a video clip that is MPEG2 1440X1080 HDV 1080.DVPROHD 720 (1.33) 25fps and needs to be converted down to PAL 720X576 for DVD. I have all the Adobe products and need advice on the best way to do this to keep good quality. Can this be tricky?

Also, it is okay to convert 720X576 video to 1024X576 for square pixels for the web (youtube)?

Thank you.

You're always going to be somewhat disappointed down-resing HD to SD. Adobe does a very decent job but there are other more complicated tools if you want to retain the nth degree of possible quality. (You'll still be disappointed with the lack of sharpness.)

For your YouTube version, you may want to consider staying at HD resolutions, either 1920 x 1080 or 1280x720. No reason to drop all the way to 576.

Thanks for the reply. Won't upscaling 720X756 to HD worsen the video quality? Isn't it better to just make it square pixels to 1024X576?

This will be my workflow to convert 1440X1080 down to 720X756. After Effects + Adobe Premier Pro + Adobe Media Encoder + Encore DVD = 720X576.
What steps would you take to make it the best possible outcome? (such as what codec to use, etc) Would dealing with rectangle pixels be an issue when doing conversions also?

Thank you.

Just take the 1440X1080 straight to YouTube.

Unless it is a matter of national security I would never cripple a HD source to SD.

The clip is originally 720X576, not HD. So I have two files, one that is 720X576 and want to convert to 1024X576 for youtube. And the other files which are 1440X1080 which I NEED to convert to 720X576 for DVD, I have no choice.

Thanks!

Convert it to 720p.

If the clip is interlaced deinterlace it (make sure you double the frame rate) and put on YouTube as 720/50P.

There's no 576p on YouTube. It'll be downsized to 480p. If that's okay with you then make it 480p yourself before uploading. Or upscale to 720p as suggested.

By the way, didn't you say it was 1.33:1? If so, where does that 1024x576 (1.778:1) come from? Or is this one really 1.78:1 and the other is 1.33:1?

[TVBroadcast]

Yes I have 1 file that is 1024X576 25fps 1.78 and another file which is 1.33 1480X1080. The reason I want to convert the 730X576 to 1024X576 is cause I want to add text and such so I guess that doesn't really matter if youtube down-converts to 480p.

However with the 1440X1080 clip, what is the best way to down-convert to 720X576 for DVD?

I don't use anything Adobe so someone else can give you the gory details. It's just a straight resize to 720x576 followed by encoding as 4:3 in your MPEG-2 encoder. I'm assuming your source is progressive. If not you'll have to perform an interlace-aware resize.

The 1440x1080 HDV video is not 4:3 (1.33:1), it's anamorphic 16:9 (1.78:1), in other words it uses rectangular pixels (wider than tall) and can be resized the same way.

Personally I would not resize to 1024x576 for YouTube because it'll be downsized by YouTube to 480p (854x480), I'd rather upscale to 720p.

So resizing 1440X1080 to 720X576 won't complex? Whats the best way to keep as much quality while down-scaling?

No, he's saying you resize in the same way but that you encode it as 16:9 rather than as 4:3 in your MPEG-2 encoder.

You can't keep quality while downscaling but downscaling to 720X576 is not particularly any worse than any other way.

You can drop both of your original clips directly into Encore which will handle all the down-converting size-matching and codec converting relatively well. What are After Effects or Premiere or AME contributing to your process?

For your YouTube version, stay at either 1920 x 1080 or 1280x720. You can do this straight out of Premiere.

Thank you all for the reply and help.



[QUOTE=smrpix;2390257]What are After Effects or Premiere or AME contributing to your process?

I'm adding effects and masking etc in After Effects and then put into Adobe premier to edit, then AME to convert, then encore for DVD.

Right, so stay at native resolution until the final step. It's still not clear whether you intend to intermix these streams or use them sequentially.
