Dear Monty

I had a go at using the freely available version of CineWorks with some JPEGs over the bank holiday, to see if you could make an MPEG out of them.

I managed to lay the JPEGs out on the time line, once I'd converted them to sprites, use a WAV file as a sound track, and save it as a playable Replay movie.

However, there is only one Replay to MPEG convertor available, called MakeMPEG, and when I tried it with the Replay file, not only was it very slow, but it also generated a floating point error, leaving an unplayable MPEG file.

I don't have the later MPEG- capable version of CineWorks, so I don't know whether that would fare any better.

If anybody reading this has it, perhaps they could have a go and tell us what happens.

However, once a RISC OS 5 version of the BeagleBoard becomes available, we will have a RISC OS system with a 600 MHz main processor and a dedicated AV processor, specifically designed for fast MPEG and MP3 playback.

At the Wakefield Show the RISC OS Open people were saying that one of the first positive benefits of this, was that we were likely to see the first real-time DVD player on RISC OS.

For the first time we will have hardware that makes digital video on RISC OS a doable proposition.

What we really need is either for the code for the latest version of CineWorks to be made open source, or, even better, for CJE to take over development and support of the product, so that it can be made 32 bit and also be properly main- tained and supported.
