Cheers Andy, you must have something on your system that I don't have on my laptop.

All my forum comments are based on or refer to my System 1.

My struggle is over! I built my (now) system 2 in 2011 when DV was king and MPEG 2 was just coming onto the scene and I needed a more powerful system to cope. Since then we've advanced to MP4 and to bigger and bigger resolutions. I was really suffering, not so much in editing (with proxies) but in encoding, which just took ages. A video, with Neat Video noise reduction applied, would encode at 12% of film speed. My new system 1 does the same job at 160% of film speed. Marvellous. I'm keeping my old system as a capture station for analogue video tapes and DV.

For what it's worth, I tested @Gra_Ham's file in a number of video editors;

VideoStudio 2023 - Crashed

PinnicleStudio 26 - played fine

Vegas 22 - would not play

The file played fine in Capcut and Davinci Resolve 20 which are free to download and use. So there are a number of free alternative editors that accept these files which eliminates the need to convert. And since it is a format that can be read by other video editors, the sample file should be sent to Magix Support to review. Perhaps it can be included in a future update.🙂

Candive, I hope that was in jest. Convert to Davinci just to avoid a recode? Even I wouldn't do that. It is clearly a "non-normal" file type; look at the framerate if nothing else, and if the Vegas can't open it, I can't see any justification for Magix to spend time developing the code to enable opening it. Far more pressing "bugs" to fix first.

Hi @AAProds

I'm serious. A new user just wants to load their video and start editing in a video editor that works. They don't necessarily desire or have the skill set to convert the file. Yes, you can download a free converter such as Handbrake or Shutter Encoder to go through the process of converting the file. It's just as easy, actually easier, to download a free editor which can read, edit and produce a movie.

I just tested this file in Shotcut and OpenShot. These two free video editors can also read/edit this file. So now my count is 5 editors; four of them free, which can read and edit this video file without conversion of this "non-normal" file format. My personal expectation is that a paid editor should meet and exceed any basic free version. So Magic developers should be aware of this file format and implement a fix for their paying customers. No excuses.

In saying that, I recommend @Gra_Ham to continue using VDL2026. It's a great editor and has so much more functionality to offer. But I would also recommend not to limit use to one editor particularly when the other tools are free and can get the job done. Learning is half the fun! 😊

The Magix editors (VDL/VPX/Vegas) are my current editors of choice. I want these products to be the best in class. Perhaps my standard is high, but in this particular case, there is no reason why VDL should not be able to read this file.

Cheers Andy, you must have something on your system that I don't have on my laptop.

I have nothing out of the ordinary I don't think - MPC-HC64, Lagarith, HuffYuv, UT Video Codec. Maybe a little less common is Hauppauge WinTV v10 and LAV Filters.

Thinking about it, the Hauppauge WinTV app does install it's own codecs to enable TV recording and playback. To quote their support site it installs "alternate codec support (M-JPEG, DivX, Cinepak codecs)". Could it be that?

Andy, I'm back on my main machine and you (and I) do definitely have something "out of the ordinary" aka a "polluted" computer. Probably the LAV filters although I also have WinTV installed. On my main machine, although the original will not open, as per @Gra_Ham 's experience, when I Copy Copy MP4 it with AVIDemux, I can open it with no issues; not so on my "cleanish" laptop.

@Gra_Ham

Graham, seeing your video on my big monitor, I'd do a re-capture. The current video isn't very good quality at all. You should get a miles-better capture even with DV or straight into Video Deluxe. Or if you still have the originals, bring them into Video Deluxe directly. If they won't import, post the MediaInfo report for the originals and we can work out how to get them in without resorting to learning Davinci Resolve.

An excellent suggestion. If we understand the camcorder make and capture device, we can suggest a workflow that will produce a codec that is readable by VDL. The OP indicated that he is capturing PAL tapes from a camcorder using PotPlayer. I must admit, I have never used PotPlayer as capture software.
