    If you need to convert your image using HDR, you can use this tool to convert your image into the EXR format. You can also apply effects to alter your HDR

    Non HD pics are low resolution with low pixel then how can we make it HD pics

    Non-HD movies cannot be transcoded into HD movies

    What about upscales

    I think too many people watch CSI and NCIS. Zooming in on security footage doesn't look pristine like it does on TV.

    More likely than converting a still image. Upscaling any image/movie works by moving pixels apart and filling the gaps, so often you get fuzzy/blurry results because the gaps are filled by approximations or averages of surrounding pixels. For movies you have the surrounding frames to provide more information, e.g. where two pixels are part of the same object or separate ones. that can help making the approximations more accurate. It would be a painstaking process and not a simple transcoding process, and no guarantee results would be that much better.

    Most formats people watch movies in are highly compressed versions using lossy compression i.e. a lot of information is thrown away as part of the compression, and when you watch a film it is uncompressed and the missing information is filled in with approximations.

    Lossy compression is much more complicated than that but yes you can`t get away from the fact that is not an RGB raw format and as you say it has to lose detail. But I really appreciate how much things have moved forward since VCD encodes (granted a lot because of hardware decoding).... a new world. Just look at a raw TS rip to see the difference!

    Ah VCD encodes - the picture would just pixelate to hell at a complex scene. Was been a bit flippant as the compression algorithms are very good and the hardware allows realtime decodes.

    Hi,
    Nowadays, some photo converters apps and programs are available online that can convert your normal pics to HD pics like Apowersoft, convertimage etc.you can take help from these and convert your images.
