Can't export to 2.35.1 ratio (720x306) to disc?

[Letty2019]

Hello again....

I created a sequence with 720 x 306 so I can give my footage a cinema widescreen look...  original footage 720 x 480. (don't laugh)

But the only PPro export to disc settings are 16x9 ?  920x1080 bluray or 720x480 for dvd.

I can't make variations on the export to disc ratio?

There are all kinds of possibilities exporting to video files, but seems restricted going to dvd or bluray.

Please tell me I don't have to add fake black bars to my footage

Thanks,

Letty

Like Jim stated, Adobe's "smart rendering" feature is merely a simple file copy for those portions of the video clip/project that don't require re-encoding. Unfortunately, neither the MPEG-2 nor the H.264 encoders that are included in Premiere Pro supports smart rendering at all; in fact, both of those encoders always re-encode everything no matter what. And what's more, there is a BIG difference between I-frame-only MPEG and long-GOP MPEG (DVD video is of the long-GOP variety). Therefore, going from I-frame-only MPEG-2 to long-GOP MPEG-2 will require re-encoding of everything no matter what.

In addition, the resolution of video, when exported to certain file formats, must be of a multiple of some given number (for example, H.264, in the MainConcept encoder, requires that the dimensions of the video be a multiple of 4 in both directions, thereby deeming 720x306 non-compliant for that codec since 4 does not divide evenly into 306).

Thanks very much RjL, great info.

The DVD spec of 720x480 is for NTSC. PAL DVDs are 720x576.

For Blu-ray, 1920x1080 is just one of several resolutions the standards support (however, only 23.976p, 50i and 59.94i are officially supported for frame rates at 1080). Others include 1440x1080 (with a 1.33:1 anamorphic aspect ratio) and 1280x720 (only 23.976p and 59.94p frame rates are supported for 1280x720), in addition to the SD resolutions 720x576 and 720x480.

You forgot 24.  Blu-ray can take genuine 24 fps.  (DVD cannot.)

Does that all sound about right?

Yes.
