Converting to GIF won't restore lost quality
Your M4V file has already undergone lossy compression. Converting to GIF preserves what's left — it prevents further degradation from re-saving — but it will not magically sharpen a blurry image or recover discarded audio frequencies.
Some metadata may not survive
Your M4V file may contain MP4 atoms, iTunes tags metadata. GIF has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.

Your M4V video is transcoded — video and audio streams are decoded and re-encoded into the GIF container. This is a lossy process that takes time proportional to the video duration.
Your M4V file is demuxed — video, audio, and subtitle streams are separated
The video stream is decoded frame-by-frame, then re-encoded with GIF-compatible codecs (typically H.264 for MP4)
The audio stream is decoded and re-encoded (or copied if the codec is compatible)
Subtitle and chapter data is preserved where the target supports it
Streams are muxed into the GIF container and the file is saved
