Same technical glitches as above, compared to the original encode of the same film also available here.
I'm not trying to be a pain, really. I'm sure you would prefer to post films as watchable and technically useful as those for which the Prelinger-branded section of the archive has been known for years. The number of improperly-encoded videos is growing larger at an upsetting rate of speed.

Re: New Films |
The quality is much better but this clip appears to be reel 3 according to the older mpeg file

Re: New Films |
I checked over my recent Prelinger backups. As a matter of routine I download every film at archive.org that looks remotely interesting, in case a useful gem is taken down for some reason, or if the archive itself becomes unavailable. I often don't examine the files for weeks or months. I also checked over another hundred or so entries I hadn't downloaded yet.
It appears, unfortunately, that the Prelinger-section films afflicted with the technical errors detailed above number over four hundred, and include everything posted since December 2011.

Re: New Films |
I'm just now seeing the new posts in this thread. We are looking into this and will try to figure out where this is happening.

Re: New Films |
Rick, I have to again agree with Frank, the visual quality of the new mp4s is undeniably better, a vast improvement over the mpegs, but yes, unfortunately I am getting exactly the same pull-down issues that Frank has so perfectly described. Luckily, I have many of the mpeg2 versions of films I make use of which, unfortunately despite their inferior quality, I would be more likely to use because of their correct pulldown which is very easy to remove.
I really appreciate that this resource has been available for so many years, and yes, I hate being a pain about it, but it would be so incredibly valuable for low/no budget filmmakers to have these files with either proper pulldown...or, even better, no pulldown at all. It would make the files smaller and many productions are being edited at 24fps these days...with pulldown added at the end of the process.

Re: New Films |
Just to be clear, what we're doing is digitizing tapes of telecine transfers made between 1984 and 2011. All are NTSC SD transferred at 29.97 fps, but beyond that they could be anything; they were transferred by various facilities at various times on various machines. While we can control the parameters by which we derive mp4s to upload, the transfers are what they are.
